SPECIFICATION forming part of Letters Patent No. 410,231, dated September 3, 1889.

Application tiled September 3, 1888. Serial No. 284,403. (No model.) Patented in England .Tuly 8, 1887, No. 9,648.

and economical manner; and it consists of` improvements upon the machine of Frank Hipgrave, patented to me under No. 353,945 and date of December 7,1886.

The apparatus employed for the feeding of the ribbon of paper, the cutting oit of the said ribbon into suitable widths for cigarettes, and the pasting of the same is practically the same as that already described in the speciiication of said previous machine, with general modifications of the driving mechanism of the paper-knife and of the pasting-roller, hereinafter -more fully described.

The feed of the tobacco is effected in the following way: The tobacco is led upon and distributed over an endless band, of silk or other suitable material, which is caused to travelby a roller, to which a suitable intermittent and regular feed is given by a ratchetwheel and pawl worked by an eccentric from the main shaft, which I consider an improvement lupon the feed mechanism as shown and described in the aforesaid patent. The tobacco is cut by a single stroke of a knife operated by a lever and cam, the latter attached in a suitable position to the main rotating shaft. One of the tables shown in the aforesaid patent for delivering the out tobacco to the pocket of the band is dispensed with, one table being found to answer all required purposes. I may by an alteration in the position of the cutting-knife with regard to the band dispense also with the other table, so as to allow the cut tobacco to drop direct into the pocket of the band.

I make several important modifications in the driving and operating mechanism of the endless band by which the cigarette is rolled to eifect the following improvements in the operation of the machine.

First. To insure a better rolled cigarette with least chance of destruction of the cigarette-paper, and with best roundness of form, I arrange to roll the tobacco in the band before the paper is rolled around the tobacco to form the cigarette. I effect this by giving a peculiar movement to the pressing-roller which closes up the pocket, as follows: This roller I mount on abell-crank, which is operated by an inside cam on the main shaft, so as `to close the mouth of the pocket and press upon the tobacco before the paper is introduced into the pocket. Then the said roller is caused to open the mouth of the pocket when the latter is about to receive the paper, and to descend and reclose the mouth of the pocket with a final grip upon the paper for the combined rolling of the paper and tobacco together to form the cigarette. Between this aforesaid niovem eut of the roller in the first and second closing of the pocket this roller iscaused to travel upward upon the band to press y the tobacco while being rolled into shape. This secondary motion of the said roller is effected by the said bell-crank (carrying the said roller) being mounted, as regards its pivot, upon the arm of another lever or l bell-crank, which, receiving motionlfrom a suitable cam uponA the mainA rotating shaft, communicates the required compoundmotion to the said pressing-roller.

Second. I have further improved the facility and certainty of the discharge of the cigarette when completed by the following modifications: The roller which opens and closes the band, .insteadof being, as described in the aforesaid patent specification, applied to that side of the band toward which the cigarette falls when thrown out, is now applied to that part of the band farthest from that side in which the pocket is formed and toward which the cigarette is discharged, thus leaving the band in a vertical position at the time of discharge of the cigarette.

Further, I drive the driving-roller of the band by an alternate fast and slow 'movement, effected by a pair of pinions being applied to the saidshaft of different diameter, and gearing into segmental wheels of correspondingly-different diameter on the main driving-shaft, which engage alternately for parts of the revolution into their respective pinions. By this arrangement the speed of the band is greatly accelerated after the cigarette is rolled, and it is thus thrown out more quickly.

In order that 1ny invention may be the better understood, I now proceed to describe the same in relation to the drawings hereunto annexed, reference being had to the letters and gures marked thereon.

Like letters refer to like parts throughout 'the drawings.

Figure 1, Sheet 1, is a general side elevation of my improved machine. Fig. 2, Sheet 2, is a plan "of same. Fig. 3,'Sheet 3, is a longitudinal section through the center of the machine, showing the right-hand section, as indicated by arrow 3, Fig. 2. Fig. 4, Sheet 4, is 'a longitudinal section through the center of the machine, showing the left-hand section, as indicated by arrow 4, Fig. 2. Figs. 5 and .6, Sheet 5, show a side and end view, respectively, of the compound mechanism controlling the rolling operation of the tobacco and the cigarette in the band. Figs. 7 and 8 are side and end elevations, respectively, of the lever motion operating the stretching of the band to throw out the cigarette. Fig. 9, Sheet 6, is a large scale scctional detail of the mechanism operating the tilting table and pasting-roller. Fig. 10 is a large scale sectional detail of the mechanism operating the paper-knife. Fig. 11 is a detail of the two-speed driving segmental Wheels and pinions controlling the traveling of the band.

A is a roll of paper fed down the inclined table a by the feed-roller B. This roller is fitted on the main driving-shaft b, which receives its motion through the gearing c c from the irstmotion shaft C and pulleys C. The roller B is covered for part of its circumferenceY with a pad of gutta-percha, leather, or other suitable material, which seizes the paper and draws it from the roller A intermittingly down the feed-table under guiderollers 1 2. Vhen that portion of the roller B which is uncovered with this coating passes over the paper, it no longer grips the paper, and the paper remains stationary, held by the gravitating guide-roller 2, which is made sufficiently heavy or weighted in customary manner. The paper is out when stationary by the knife D, which is operated by the lever 3 and cam 4. (Shown in sectional detail, Fig. 10, Sheet 6.) The cut piece of paper then rests upon the tilting table el, and is held while resting there by the finger 5, Fig. 9, Sheet 6. This finger pivots on a center, and is allowed. to press upon the paper, and is lifted, when required, by the cam G and pivoted connection 7, Fig. 9, Sheet 6. Vhen the paper so cut rests upon the tilting table d, one edge is brought up to the pasting-roller e, fitted in the mouth of the paste-trough E, by the pivoted lever F, operated by the cam f. The paper, when pasted, as described, is now ready to be seized by t-he tobacco on the rollingband G after the tobacco has been rolled. The tobacco is fed on the endless band H, of silk, glazed linen, or other suitable material, which is caused to travel by a roller h, h being the carrying-roller. .A suitable intermittent and regular feed is given to the drivingroller h by a ratchet-wheel 3 and pawl 9,Figs. 1 and 2, Sheets 1 and 2, the pawl being attached to a lever which receives its necessary intermittent motion from the eccentric 10 on the main shaft. The intermittent movement of the ratchet S is transmitted through the gearing 1l, 12, 13, 14, and 15. Upper pressing-rollers h2 h3 and a further under roller h4, to press the tobacco as it is delivered to the knife, are mutually geared together in pairs, and are connected to the driving-wheel h by a carrying-pinion 16, of double Width. The tobacco is cut by the single stroke of a knife J, Fig. 3, Sheet 3, operated by a lever j, anda slotted cam in a disk 17 on the main shaft l), Fig. 1, Sheet 1, and falls into a trough or table 7c on an oscillating standard K. The oscillation of this table is effected bythe crank k and the pivoted lever 13, operated from the cam 19, Figs. 1 and 4, Sheets 1 and 4, on the main shaft. This oscillation ofthe table delivers the cut tobacco into the pocket of the rolling-band G, the pocket being formed by fingers 20, dead weighted and sliding in the slotted guides 21, so as to form a pocket in the slack of the band, when `the tightening-roller L permits the pocket to be so formed. The endless rolling-band G is constantly rotated by the rollers 22 and 23, which are geared together, as represented by dotted circles in Figs. 1, 3, and 4, Sheets 1, 3, and 4, and in detail in Fig. 11, Sheet 6. The roller 22 receivesits motion by the double pinion 24, gearing into two segmental wheels 25 and 26 upon the main driving-shaft, Fig. 1, Sheet l, and detail, Fig. 11,Sheet G. By the alternate gearing of these segmental wheels 25 and 26, of different diameter, into their respective pinions p25 p26, Fig. 11, the banddriving rollers 22 and 23 are caused to Vvary in their speed of revolution, so that the travel ofthe band is greatly accelerated after the cigarette is rolled, and it is thus thrown out more quickly.

To insure a better rolled cigarette with least chance of destruction of the cigarette-paper and with best roundness of form, cause the band to roll the tobacco before the paper is seized, and the paper is afterward rolled around the tobacco to form the cigarette. I effect this by giving a compounded motion to the pressing-roller 27, Figs. 5 and 6, Sheet 5. This roller is mounted so as to turn freely on the extremity of the bell-crank M. The pivoted motion of the pressing-roller is effected by the bell-crank arm 28, which, provided with an anti-friction roller, engages in a slot of another oscillating lever 29, Figs. 1 and 5, Sheets l and 5. The oscillation of the slotted lever 29 is effected by the link 30, connected to the pivoted lever 31,

operated'by the slotted cam 32 on the main i shaft, Fig. 5, Sheet 5. This motion causes the pressing-roller 27 to approach to or recede from the opposite side of the pocket in the band, as desired. At the same time the pressing-roller 27 receives a vertical motion by the rock of the bell-crank M, on one eX- tremity of which the said pressing-roller is mounted, the other end of this bell-crank M receiving a reciprocating motion by a cam 33, Figs. 1 and 5, Sheets l and 5. This compounded vertical and horizontal movement of the pressing-roller 27 causes it to close the mouth of the pocket in the band so soon as the tobacco is received and to press upon the tobacco before the paper is introduced into the pocket. Then the said roller is caused to open the mouth of the said pocket to receive the paper and to descend and reclose the mouth of the pocket with a final grip upon.A the paper by the tobacco in contact with the band, for the combined roll of the paper and tobacco together to form the cigarette.

v Fig. 7, which, situated onrocking levers l, re-

ceives the necessary movement to communicate the tightening to the band bythe setscrew 34 from the bell-crank N. The setscrew 34 permits adjustment as to the throw of the roller L as compared with the throw of the bell-crank N, which by varying the tightness of the band enables the apparatus to roll and make cigarettes of various diameters with a uniform pressure upon the tobacco and cigarette in the dierent cases. The bell-crank N receives its movement from an-A other bell-crank O through the link n, and the latter bell-crank O receives its movement through the link p and pivoted lever P, Figs. l, 4, and 7, Sheets 1, 4, and 5. This stretching or discharging roller L is now applied to the part of the band farthest from the opposite side toward which is the pocket, and over 1. The combination, with the driving-shaft l) and means for continuously rotating the same, of the eccentric and rod 10, transmitting rolling band G, means for rotating the same,

motion therefrom, the pawl 9 and its carrying-lever actuated by saidrod, the ratchet by said roller h, and the tobaccopressin g rollx ers h3 h4, substantially as described.

2. In combination with an endless cigaretterolling band G, means for rotating the same, and suitable supporting, tightening, and

bight-forming devices, the pressing-roller 27,

the bell-crank 28, carrying said roller, the bell-l lcrank M, carrying said bell-crank 28, the 4cams 32 33, means for rotating said cams, and

lever-connections transmitting motion from the respective cams to the respective bell-` cranks, substantially as described, for the purpose set forth.

3. In combination with an endless cigaretteand suitable supporting, bight-forming, and pressing devices, the tightening-roller L, located at the side of the band opposite that on which the cigarette is discharged, and means for carrying, actuating, and adjusting said said levers relatively to said bell-crank, substantially as and for the purposes described.
